Sagot :
Answer:
B. [tex]\frac{14}{625}[/tex]
Step-by-step explanation:
Total paper in the hat:
2 blue + 6 red + 10 yellow + 7 purple = 25 total pieces of paper
P(AB) = 7 / 25 x 2 / 25
A is the probability of pulling a purple paper
B is the probability of pulling a blue paper
Answer:
14/625
Step-by-step explanation:
probability = favorable outcomes/total number of outcomes
First find the probability of drawing a purple piece of paper.
There are 7 pieces of purple paper.
Add all the amounts of colored paper together to get the total number of outcomes.
2 + 6 + 10 + 7 = 25
The probability of drawing purple is 7/25
Now find the probability of drawing blue. There are 2 blue pieces of paper. Since he replaces the purple paper the total stays at 25.
The probability of drawing blue is 2/25
This is a compound probability problem, so multiply the two probabilities together.
7/25 x 2/25
14/625
